A Systems Engineer is troubleshooting the connectivity of a test environment that includes a virtual security appliance deployed inline. In addition to using the virtual security appliance, the Development team wants to use security groups and network ACLs to accomplish various security requirements in the environment.

What configuration is necessary to allow the virtual security appliance to route the traffic?

Disable network ACLs.

Configure the security appliance's elastic network interface for promiscuous mode.

Disable the Network Source/Destination check on the security appliance's elastic network interface

Place the security appliance in the public subnet with the internet gateway
Place the security appliance in the public subnet with the internet gateway
Suggested answer: C

Explanation:

Each EC2 instance performs source/destination checks by default. This means that the instance must be the source or destination of any traffic it sends or receives. In this case virtual security appliance instance must be able to send and receive traffic when the source or destination is not itself.

Therefore, you must disable source/destination checks on the NAT instance."

An AWS account includes two S3 buckets: bucket1 and bucket2. The bucket2 does not have a policy defined, but bucket1 has the following bucket policy:

Amazon SCS-C01 image Question 198 7316 09162024005923000000

In addition, the same account has an IAM User named “alice”, with the following IAM policy.

Amazon SCS-C01 image Question 198 7316 09162024005923000000

Which buckets can user “alice” access?

Bucket1 only
Bucket1 only
Bucket2 only
Bucket2 only
Both bucket1 and bucket2
Both bucket1 and bucket2
Neither bucket1 nor bucket2
Neither bucket1 nor bucket2
Suggested answer: C

Explanation:

Both S3 policies and IAM policies can be used to grant access to buckets. IAM policies specify what actions are allowed or denied on what AWS resources (e.g. allow ec2:TerminateInstance on the EC2 instance with instance_id=i-8b3620ec). You attach IAM policies to IAM users, groups, or roles, which are then subject to the permissions you’ve defined. In other words, IAM policies define what a principal can do in your AWS environment. S3 bucket policies, on the other hand, are attached only to S3 buckets. S3 bucket policies specify what actions are allowed or denied for which principals on the bucket that the bucket policy is attached to (e.g. allow user Alice to PUT but not DELETE objects in the bucket). https:// aws.amazon.com/blogs/security/iam-policies-and-bucket-policies-and-aclsoh- my-controlling-access-to-s3-resources/
